    摘要: An oxidation catalyst of the perovskite-type compound oxide which comprises, as A site, a mixture of rare earth elements from ores, part of which is replaced by at least one element selected from alkali metals, alkaline earth metals and rare earth elements other than the ore-originating elements, and a transition metal as B site. The surface atomic ratio of the mixed rare earth elements and the transition metal is in the range of 1.0:1.0 to 1.1.:1.0. A method for preparing the compound oxide is also described.

    摘要: For the preparation of a catalytic composite for purifying exhaust gases, first, at least one perov-skite-type compound oxide of the formula RMO.sub.3, where R is La or a combination of La and Ce, and M is Co, Mn or a combination thereof, is supported together with cerium dioxide and alumina sol on a heat resistant carrier made of an inorganic oxide selected from the group consisting of cordierite and mullite, and then iron and palladium are further supported together thereon. As a result, a catalytic composite having a high degree of oxidation activity at low temperatures and also having excellent heat resistance can be obtained.

    摘要: The digital camera 1, when a length-direction range expanding button 14 or a breadth-direction range expanding button 15 is operated, changes the length-direction and breadth-direction image pickup effective ranges of a solid state image pickup device 40 using an image pickup effective range setting table 41. Due to this, there can be obtained picked-up images with a length-to-breadth ratio changed without rotating the main body of the digital camera 1. Also, since the length-direction and breadth-direction image pickup effective ranges are adjusted such that the area of the image pickup effective ranges of the solid state image pickup device 40 can provide a substantially constant value, there can be always obtained an image of good quality.
